Rottneros to Spend SEK 77 Million on Evaporator Upgrade
Dec. 17, 2009 - Swedish market pulp producer Rottneros said that its Board of Directors has approved an SEK 77 million capital expenditure (approx. USD 10.5 million) to upgrade the evaporator facility at the company's Vallvik Mill in Sweden.
The evaporator project is part of Rottneros' plan to increase the pulp mill's capacity.
"The increased capacity for evaporation means that more of the mill's process water can be evaporated, which in its turn makes it possible to recover and burn the organic material. This increases Vallvik's output of bioenergy," said Ole Terland, president and CEO of Rottneros.
"What's more, by using special equipment, steam from the evaporation is divided into the bio-gas that is burned and the water vapor that is condensed into pure water. Both of these are recycled while producing pulp and reduce the need for oil plus the quantity of wastewater," Terland said. "This reduces the impact on the external water environment and the external water treatment facility that is planned can be of a much smaller size and cost less."
The project is scheduled for the fourth quarter of 2010 and work will take place in conjunction with the mill's annual maintenance downtime.
The Vallvik Mill employs 180 people and produces two grades of long-fiber sulphate pulp: fully bleached sulphate pulp, ECF (Elemental Chlorine Free) and unbleached sulphate pulp, UKP (Unbleached Kraft Pulp). The mill has a permit to produce 220,000 tonnes.
In 2008, the mill produced 200,500 tonnes of pulp, nearly matching its 2007 production record of 201,400 tonnes..
